Guys, I've been trying to figure out what the avengers' classes would be in an rpg
Hulk=Tank
Black Widow=Thief/Stealth fighter
Hawkeye=Ranged fighter
Thor=Mystic
Captain America= Tactician
I have no idea what Iron man would be. If you have any corrections, or know what Ironman would be, please feel free to reply.

CA as tank makes more sense to me (with the indestructable shield and all)
Hulk=Warrior(close combat offensive)
Agreed on Hawkeye, Thor an BW
As for iron man... somwhat vaguely defined, but some kind of burst offense class (strong early on, gets weaker in longer fights). Can be applied to any kind of damage class, but often a mage. You know, because of the laser beams he can use exactly once and the always running out of juice in a crucial moment.
